Isolation, structural elucidation, and cytotoxicity of three new ent-kaurane diterpenoids from Isodon japonica var. glaucocalyx.
Three new ENT-kaurane diterpenoids, glaucocalyxin H ( 1), glaucocalyxin I ( 2), and glaucocalyxin J ( 3), together with four known diterpenoids ( 4- 7), were isolated from the leaves of Isodon japonica Hara var. glaucocalyx. Their structures were elucidated by spectroscopic analysis, and the structures of compounds 2 and 3 were further confirmed by X-ray crystallographic analysis. Compounds 1, ...
متن کامل16-membered lactone compounds from izenamicins-producing microorganism.
Previously, we reported a series of 16-membered macrolide antibiotics, designated izenamicins, produced by Micromonospora sp. YS-02930K1}. In the course of screening for intermediates of izenamicins, we obtained five 16-memberedlactone compounds and examined the biosynthetic pathways of izenamicins B2 and B3 after lactone formation. In this paper we describe the isolation, characterization and ...
متن کاملGreen synthesis of silver nanoparticles using (Eryngium Campestre) leaf extract
Biological synthesis of metallic nanoparticles is considered as a fast, eco-friendly, affordable and easily scalable technology. Also, the nanoparticles produced by plants are very stable. In this study, the focus is on the synthesis of silver nanoparticles using extract of eryngium campestre. The effective parameters such as concentration of silver nitrate, pH, temperature and time, size and m...
